Abstract: A medical device includes a replaceable or disposable sheath and laparoscopic sensor, which is at an end or tip of a laparoscopic tube. A durable or processing unit fits into and is enclosed by the disposable sheath, such that the processing unit connects to and operates in conjunction with a light engine of the sheath, to form a laparoscopic oximeter. This oximeter can measure oxygen saturation laparoscopically. The sheath can be disposed of after a single use. The processing unit can be removed from a used sheath and then used multiple additional times with clean, unused sheaths.

Abstract: A method for housing a reusable portion of an oximeter device in a sheath includes providing the oximeter device as a probe unit and a laparoscopic tube separated from each other. The probe unit is handled by a first operator in a nonsterile environment and the laparoscopic tube is handled by a second operator in a sterile environment. The first operator connects the probe unit and the laparoscopic tube to form the oximeter device. The sheath is coupled to the laparoscopic tube in a folded configuration and is pulled by the second operator to enclose the probe unit. The oximeter device is in the sterile environment when the probe unit is in the sheath. The oximeter device is for use in an intraoperative procedure and the sheath inhibits the probe unit from contacting contaminants so that the probe unit is reusable, whereas the laparoscopic tube can be disposed of.

Abstract: An oximetry device sealed in a sheath directs a user to allow the oximetry device to make oximetry readings at a number of different tissue locations of a patient and average two or more of the oximetry readings by directing the lifts and placements of the oximetry device and sheath to and from the different tissue locations and detecting the lift and placements. The averages are generated and displayed on a display of the device for the oximetry readings if the lifts are made while use directions for the lifts are displayed on a display of the oximetry device. The averages are not generated if the lifts are not made while the user directions for the lifts are not displayed. The averages are simultaneously displayed with the oximetry readings which are instantaneous measurement for patient tissue.

Abstract: A laparoscopic medical device includes an oximeter sensor at its tip, which allows the making of oxygen saturation measurements laparoscopically. The device can be a unitary design, wherein a laparoscopic element includes electronics for the oximeter sensor at a distal end (e.g., opposite the tip). The device can be a multiple piece design (e.g., two-piece design), where some electronics is in a separate housing from the laparoscopic element, and the pieces (or portions) are removably connected together. The laparoscopic element can be removed and disposed of; so, the electronics can be reused multiple times with replacement laparoscopic elements. The electronics can include a processing unit for control, computation, or display, or any combination of these. However, in an implementation, the electronics can connect wirelessly to other electronics (e.g., another processing unit) for further control, computation, or display, or any combination of these.

Abstract: An oximeter probe includes a probe unit or a base unit and a probe tip where the probe tip has a number of sources and detectors that can be accessed individually or in differing combinations for measuring tissue oxygen saturation at different tissue depth in tissue. A processor of the oximeter probe controls a multiplexer that is coupled to the detectors for selectively collecting measurement information from the detectors via the multiplexer. The oximeter probe is user programmable via one or more input devices on the oximeter probe for selecting the particular sources and detectors to collect measurement information from by the processor.

Abstract: An oximeter device has a replaceable probe tip. The probe tip can be removed or detached from the probe unit and discarded. A replacement probe tip can be attached to the probe tip. The replaceable probe tip allows the probe unit to be reused many times, each time with new sterile probe tip.

Abstract: A laparoscopic medical device includes an oximeter sensor at its tip, which allows for making oxygen saturation measurements laparoscopically. The laparoscopic medical device includes a probe unit and a laparoscopic tube that detachably connects with the probe unit so that the laparoscopic tube can be replaced for different patient surgeries and the probe unit can be reused. The probe unit includes a number of optical fibers and the detachable laparoscopic tube includes a number of optical fibers where tips of the fibers of the probe unit and laparoscopic tube connect end to end. Cores of the transmitting optical fibers have smaller numerical apertures and smaller diameters than cores of the receiving optical fibers to facilitate a high percentage of light transmission even when the optical fibers are misaligned at their contacting ends.

Abstract: An oximeter sensor probe system includes a sensor probe unit that is connected by a wire to a sensor probe electronic module. The sensor probe electronic module connects wirelessly to a medical device console, which can be a phone, tablet, or other mobile device. And the mobile device can connect to a network or the Internet (e.g., the Cloud). Alternatively, the sensor probe electronic module can directly to the network or the Internet directly without a medical device console. The medical device console can execute an application and show on its display oxygen saturation and related measurements obtained through the sensor probe unit.
